IMPROVEMENT IN WATER-SUPPLY PIPES.

Specification folining part of Letters Patent No. 196,745, datedNovember 6, 1877; application filed Toall whom it may concern:

Be it known that I, CHAnLEs L. DRmss LEIN, of Chicago, county of Cook,and State of Illinois, havev invented a new and useful Improvement inWater-Supply Pipes, which is fully describedy in the followingspecification, reference bein ghad to the accompanyin gdrawings, inwhichl Figure 1 represents a plan view of asquar or block with myauxiliary water-pipes laid. around it; and Fig. 2, a detail section, onan enlarged scale, taken on the line x x, Fig. 1.

The object of my invention is to provide for a large supply of water,incase of iire, at the immediate locality of there, which can be madeavailable for the supply of water to an engine placed 'close by theburning building.

The invention consists in auxiliary waterpipes laid around a square ofbuildings, or a portion thereof, above the ground, and connected withthe main supply-pipes, so that the water from the latter may be turnedinto the former at will.

It also consists in arranging the auxiliary pipes in a slightly-inclinedposition, so that v the water-may be entirely drained from them when notin use. y

It also consists in special combinations of devices for connecting theauxiliary pipes with the mains, and providing for the coupling of hoseto the former, all of which will be hereinafter more fully set forth. h

In the drawings, A represents the sidewalk between the houses andcurb-stone; B, thepavement of the streetadjacent; and G, the supply-pipeor water-main laid along the street under ground, in the usual manner.An auxiliary water-supply pipe, D, is laid above the ground, extendingalong next to the curb. This pipe is preferably arranged upon two sidesof the square, as shown in F-ig. 1 of the drawings, so that two pipeswill be employed to surround the entire square. These auxiliary pipesare connected with the main supply-pipes in two opposite streets atdiagonally-opposite corners of the square by means of service-pipes E,one of which is connected to each end of the pipes D, and is extendeddown into the ground, and then outward, to connect with a T branch pipe,

any other point, and therefore all water may be drained from them, aftercommunication with the main pipes is closed, by means of an intermediateoutlet, conveniently located for this purpose immediately above orunderneath the ground.

In the drawings a plug, H, is represented as inserted in the ends of theservice-pipes, where they join the branch coupling F, by means of whichthis draining of the auxiliary pipes may be accomplished; butan outletmay be provided at any other point which will permit the same result tobe effected.

Thepipes D are provided along their entire length with suitablehose-couplings I, controlled by a stop-cock or valve of any ordinaryconstruction. These couplings may be arranged at such intervals alongthe street as maybe desired, one being placed opposite every house inthe square, if wished.

The pipes D are made of large size, so as to take a large quantity ofwater from the streetmain, and therefore, whenever a re occurs, severalengines can be located close -to the burning building, and supplied withwater from the pipe D by coupling to the plugs I. y Itis evident that bythis means the difficulty of forcing water through long lengths of hosefrom an engine stationed at some distance from the re is entirelyobviated, and thereby a great saving in the cost of hose is effected,

and also the force of the engine is almost entirely utilized in throwingwater directly into or upon the building, instead of losing a largepercentage in forcing the waterlong distances through ho se. The supplyof water will always be sufficient and in readiness, and obtained bypipe. The connections between thel branch' pit, ifdesired, so as to bereadily:

simplyturning the plugs Gat one y or `both ends ofoneior niorefof the,auxiliary pipes, `thereby opening communication with the mains.

After use, and especially in cold Weather, communication between themains and auxiliary pipes should be closed, and the latter drained, asabove described. In ordinaryl weather the plugs I, at the lowest pointsof the pipe, may be used for this purpose; butti when there is danger offreezing the drainingoutlets should be' under ground.

It is not absolutely necessaryto put these auxiliary pipes around everysquare in aH city, as it is evident that by surrounding each alternatesquare there would be one of these supply-pipes in every street, withinconvenient distance of the `houses thereon; but of course the supply ofWaterwill be much greater if `the` auxiliary pipes are laid around everysquare.

Instead of the arrangement described, the pipe D may be laid along thestreet parallel to the main C, and connected at everysquare, orl two ormore squares, with `the main, `as described, so that the water from themain .may be diverted into the auxiliary pipe,and returned again to `thesaine main pipe. The auxiliary pipe should be made as large, orl nearlyso, as the main, where the latter is small, so that nearly the entiresupply of water may be, diverted from the main into .the auxv iliarypipe.

The couplings in the auxiliary pipes lmay` also beused for attachinghose directly thereto d without the intervention of an engine forlserv-` ice in case of ire,or anyfother Ause desired; and standfpipes 7Aare employed, `they `may be coupled tothe auxiliary pipes wheneveroccasion requires.

Having thus described my invention, what Iclaim as new, and desiretosecure by Letters Patent, is-

1. The auxiliary Water-supply pipes D, laid in the `street above ftheA`ground or pavement, around or along a square or block of buildings,

and provided with a series of plugs, I, in combination with thewater-.main C, with which the auxiliary pipe is connected, so that watermay be admitted to or shut oli therefrom, substantially as and for thepurpose set forth.

` 2. The auxiliary pipes D, extending around` vtWo sides of a blockorsquare, connected with the mains in two opposite streets, `and laidAin an inclined plane,"as describedfsubstantally as and `for the purposeset forth. y t

3. The auxiliary pipes 1),;arrangeduponthe` street, above thesurfacethereof, as l described,` in `combination with the mainsupply-.pipes C, the serviceor `connectin g pipes E,coupling F, andvalves Gr, substantially as described.

4. The service-pipes E,in`co1nbination=with y the branch coupler F,main`pipe G, valves G, and plugs H, substantiallyas and `for the purpose setilibrth, p
